WEFT-REPLENISHING LOOM.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed. December 22, 1920. Serial No. 432,443.

T 0 all whom it may concern:

Be it known that I, SrMnoN S. JACKSON, a subject of Great Britain, residing at Hyde Park, Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Weft-Replenishing Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to bobbin-changing weft-replenishing looms, and more particularly to the means employed in such looms for the control of the shuttle-feelers and transferrer-dogs of the replenishing mechamsm.

The invention consists in improved means for the purpose just mentioned.

The drawings show, partly in section, certain of the parts of a loom having an embodiment of the invention applied thereto.

Referring to the drawings,-

I provide a transmitter-rocker 1, whichI mount at the front of a loom, adjacent the controllerrockshaft 2 of the weft-replenishing mechanism. .I combine it operatively with the said rockshaft, so that when the weft-detectingmechanism of the loom causes the rockshaft to be rocked in the direction of the arrow near it in the drawings, in order to bring about replenishment of the shuttle on the lay with weft or filling, the rocker is rocked in unison with the rockshaft. I combine it operatively with the shuttle-feeler 3 and the transferrer-doge, so that this rocking of the rocker causes the shuttle-feeler to be swung rearward from its normal position represented in the drawings into feeling position, and the transferrer-dog to be swung upward from its normal depressed position shown in the drawings so as to place its rear end in the path of the hunter 5 carried by the lay-beam 6. The drawings show a shuttleefeeler 3 of the old overhead type, mounted as heretofore upon a pivot 3 at the inner face of the stationary plate 7 which supports the horizontally extending stud 8 on which the rotary drum D of the magazine or feeder is mounted. It is connected with the transmitter-rocker 1 by means of a connecting-rod 9 that is joined at its rear end to an arm of the shuttle-feeler extending upward above pivot 3 and at its front end to an upwardlyextending arm 1?- of the rocker.

The transferrerdog 4 herein, as usual in practice, is combined with a dog-carrier 4 that is pivotally hung at 1 upon a downwardly-extending arm a of the transferrer or hammer 45 The said transferrer, as usual, is mounted pivotally upon a stud 4 projecting outwardly from the supportingstand 7 fixed upon the loom-frame 10. The usual spring for holding the transferrer in its uplifted normal position is indicated at 4?. The usual spring applied in connection with'the dog-carrier pivot at 4, and acting in connection with the said dog-carrier so as to keep the transferrer-dog down in its normal position shown in the drawings, is not shown,'but' in practice may be applied as heretofore. The transferrer-dog 1 is connected with the transmitter-rocker l by means of a connecting link 11 that is joined at its upper end to the dog-carrier 45* by means of, a pivot 11, the lower end of the said link having therein a longitudinal slot 11 in which works a stud or pin 11 projecting from a downwardly-extending arm 1 of the transmitter-rocker.

The transmittenrocker 1 is combined operatively with the controlling rockshaft as by means ofa rearwardly-projecting finger 1 of the said rocker, a give-away lever 12 pivoted upon a downwardly-extending arm 2 of the said, rockshaft and having a forwardly-projecting arm which engages with the under side of said finger, a pull-spring 13 that acts downwardly upon a rearwardlyprojecting arm of the give-away lever, and a stop 14. carried by the rockshaft. In this instance, stop 14L is formed upon a pad-lever 14 fixed upon rockshaft 2. The said stop is in front of the upwardly-extending arm 1 of the transmitter-rocker. WVith the parts thus combined and arranged, the pull of the spring operates to keep them in their normal positions shown in the drawings. The said pull, by acting on the rearwardly-extending arm of the give-away lever causes the forwardlyextending arm of the latter to bear upwardly against the finger of the transmitter-rocker, thereby keeping the upwardlyextending arm 1 of the rocker pressed forward against therear side or stop 14: on padlevervl P. With arm 1 in contact with the stop 14., the continued pull of the spring, acting through the pivot by which the giveaway lever is connected with arm 2*, keeps the rockshaft 2 turned in the direction opposite that indicated by the arrow, with padshaft and the transmitter-rockshaft occupy the positions just described, the shuttle-feeler is kept retracted forwardly in the position occupied by it in the drawings, and the transferrer-dog is kept lowered into its illustrated position.

lVhen the controlling rockshaft 2 is rocked in the direction of the arrow, the tension of the spring acts through the give-away lever against the finger 1 to cause the arm 1 to remain in contact with stop 1 so that the transmitter-rocker is yieldingly actuated to rock'in unison with the rockshaft, thereby actuating the shuttle-feeler and transferrerdog so as to swing the former rearward into shuttle-feeling position, and swing thelatter upward into the path of the bunterf5 carried by the lay. In case the shuttle 15 occupying the shuttle-box 16 on the lay, instead of being fully home within the shuttleboX in proper position for a fresh bobbin 6 to be inserted into the same fromthe magazine or feeder by the action of the transferrer, should be part-way displaced out of the' shuttle-box, i. 6., should project far enough from the mouth of the shuttle-box to strike against the end of the shuttle-.feeler as the lay swings forward, the forward movement thereby communicated to the r The give-away lever and spring will yield to permit such reverse turning of the rocker and lowering of the transferrer-dog.

I provide for a toggle-like action by means ofwhich the shuttle-feeler, after having been moved rearward into feeling position, .will be -moved forward as a'result of the actuation of the transferrer through engagement of bunter 5 with the transferrer-dogas the layswings forward. Tothis end, the parts are arranged so that-the nor mal position of pin 11? atthe lower end of link 11 is located where a linedrawn from such pin to the axis around which the trans- 'ferrer rocks will pass forward of the pivots vdog as the lay swings forward, will act, as

the transferrer is actuated to transfer a bobbin from the magazine or feeder tothe gle-arrangement. thereby occasioning a rocking of'the transmitter-rocker 1 so that he t ee ls wil e o ed for ar V .tle-feeler and transferrer-dog. shuttle 15 onthe lay, to straighten the ,tog-

from its shuttle-feeling position toward its 7 normal position shown in the drawings. The give-away device yields to permit the said rocking of the transmitter-rocker.

The construction, etc., of the parts may be varied more or less in practice.

In a weft-replenishing loom, the combination with a controlling rockshaft having a pad-finger, a give-away lever pivoted upon an arm of the said rockshaft, a'shuttle-feeler, and a transferrer-dog,of a transmitter-rocker having an arm'engagedby said lever, a link intermediate the rocker and the shuttle-feeler, a link intermediate the rocker and the dog, andaspring acting through the said leverto keep the rocker engaged with the pad-finger, and also acting through the lever and rocker to keep the rockshaft in normal position, with the padfinger against its abutment, and the-shuttlefeeler and transferrer-dogin their normal inoperative positions.
